iCarly Easter Egg - Josh in the Attic

In the iCarly episode "I Christmas" when Carly wishes for Spencer to be normal, she goes to the iCarly studio, which was originally the attic, and there were boxes that said things like "Josh's things" and "Josh's T-Shirts." Josh was a character in Dan Schnider's show "Drake and Josh," which also had the same creator as "ICarly."
